VACUUM GLEQNI'NG APPARATUS.

To all whomvit may concern: Be it known that'I, PITMAN W. PARKER, a citizen of the United States .of America, re-

siding at San Diego in the county of San;v

Diego and State of (laiifornia, have invented certain new and useful Improvements in Vacuum Cleaning Apparatus, of which the following is a specification.

This invention relates to vacuum cleaning apparatus and more particularly to a brush head for apparatus of this character, the object of the invention being to locate a longitudinally adjustable brush in the mouth of a flaring vacuum tube or pipe in such man-' ner'that the suction may be varied by the longitudinal movement of the brush with relation to "the tube.

It is also an object of the invention to provide a rotatively mounted brush and to provide additional means for varying the suction, the rotation of the brush being accomplished, if desired, by the passage .of air through the suction or vacuum tube.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawing Figure 1 is a longitudinal sectional view of a brush head constructed in accordance with the, invention; Fig. 2 is an end view thereof, and Fig.

3 is a s1de elevation of a portion thereofillustrating a vent controlling ring, hereinafter described. Like numerals designate corresponding parts in all of the figures of the drawing;

Referring to the drawing the numeral 5 designates the suction or vacuum tube forming a portion of a vacuum cleaningv apparatus. This tube is provided with a flarlng mouth portion 6 and is spanned bythe fixed bars 7. Mounted for rotation in these bars is a shaft 8, which is held against endwise movement bymeans ofits collar 9, located in the housing 10. 'A fan or propeller l1 is mounted upon the inner end of the shaft so that the rush .of air through the tube 5 will act thereuponto impart rotationttothe Y shaft and the arts carried thereby. A-frustocomcal head 12- is threaded upon shaft 8 atv 13, and is bound in any adjusted osition with relation to said shaft by the lhck nuts 14. This head has secured thereto an annular brush 15. This brush is secured to the head by fastening devices 16 which pass through a flange 17 of the brush. Openings '18 are formed through the wall Specificationoi Letters Patent. Raci m; Application filed October 10, 1910. Serial Fatima;

of the tube 5 between 'thefrustoconical head and the fano'r propellerkan'd openings 19 ada ted to registertherewith are formed in a ring 19 which encirclesthetube and which is mounted :thereon in such manner that it maybe turned to bring the openings 19' into or out of registry withopenings 18 when desired. 4 I

The operation of the d'eviceis as follows With the openings of ring 19 out of registry, all oft-he air drawn into tube- 5 must ,pass between "the brush and frustoconical -head and the wall of tube 5. Itfollows therefore that the velocity of this air-will -be-determined by the longitudinal adjustment of the brush and head with relation to the flaring mouth portion 6 of the tube. It is a parent that the farther the frustoconical ead is screwed in, the smaller will be the passage, way between said head and the flaring mouth portion of the tube. A further means of controlling the suction resides in the ring 19. By turning this ring so that itso en'ings register or partially register with t e openings 18 of tube 5 the vacuum is broken to a corresponding degree and the suction is'correspondin 1y regulated. The importance of being a le to regulate .-and

controlthe suction to a,'nicety' wi1 l -he apparent' 'rwhen-it" is considered that in some rugs or carpets with considerable nap where the dirt must be drawn past consi erable obstruction and where a suctionof concases it desiredto use'the" apparatus upon siderable force can do no harm, while in other cases the apparatus is used upon coated walls where too great a suction would be likely to remove portions of the wall coating. Rotation may be imparted to the brush by means of fan or propeller 11.

Fromthe foregoing description it will be seen that simple and eflicient means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are .well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction "*setyforth but includes within its purview ysuchlchangesy as mayfihgmade within the scope of the appended Having described my invention ,what I claim is '-1."In avacuum cleaning apparatus, the combination with a suction tube having a flaring mouth, of a 'brush'mounted in the month of said suction tube and longitudinally adjustable therein, and means actuated by the passage of air through said tube for imparting rotation to said brush.

2. Ina vacuum cleaning apparatus, the

combination with a suction tube having a flaring mouth, of an annular brush mounted in the mouth of said suction tube and longitudinall adjustable therein, and means actuate by the passage of air through said tube for imparting rotation to said annular brush.

3. In a vacuum cleaning apparatus, the combination with a suction tube having a flaring mouth, of a frustoconical brush can rying head mounted in said flaring mouth and being longitudinally adjustable with relation to said tube and an annular brush secured to said head.

4. In a vacuum cleaning apparatus, the combination with a suction tube having a flaring mouth, bars spannin said suction tube, a shaft mounted in said ars, a frustoconical brush carrying head mounted upon said shaft and longitudinally adjustable .said shaft and longitudinally ad'ustable upon said shaft, a brush carried head which projects beyond the outer end of said tube, means for holding said shaft against endwise movement, and means mounted upon said shaft for imparting rotation to the brush carrying head, said means being actuated by the passage of air through said tube.

In testimony whereof I afiix my signature in presence of two witnesses.
